    Not So Stealthy: China Can Reportedly Track Pentagon's 'Undetectable' F-22s

    The Chinese military is said to have developed capabilities which allow Beijing to detect and track some of the best aircraft in Washington's arsenal, including the fifth-generation Lockheed Martin F-22 Raptors, which some have called virtually undetectable.

    An upgraded version of the Chinese Phased Array Radar, as well as the KJ-2000 and KJ-500 airborne early warning and control systems could well cope with the task, People's Daily Online reported, citing military expert Yin Zhuo.

    The remarks came after unconfirmed reports surfaced that the Chinese military detected F-22s over the East China Sea. The PLA is said to have sent helicopters and a warship to the area. In addition, fighter jets were prepared to join other forces if requested.

    The incident took place on February 10.

    Initial reports did not specify the type of the aircraft or the country the plane belonged to, but Yin Zhuo mentioned that if the planes were F-22s then the Chinese could track them.

    "In fact – it's very possible that China can track the Raptor. Stealth is not a cloak of invisibility, after all. Stealth technology simply delays detection and tracking," defense expert Dave Majumdar wrote for the National Interest. "Even combat-configured F-22s are not invisible to enemy radar, contrary to popular belief."

      WW3 is here, what Chinese project? Serbians shot down the F-117 with Neva-M system from the 60-70's.

      "There was just luck the Serbian military did not have any "up to date" radars but old radars that did not use 3D technology. These radars from the early 60's P-12 Yenisei is something NATO or the Americans did not count on. "

      If I read carefully one of your links, I can see this :
      "A Yugoslav Army 250th Air Defense Missile Brigade 3rd battery equipped with S-125 system managed to shoot down an F-117 Nighthawk stealth bomber on March 27, 1999 during the Kosovo War (the only recorded downing of a stealth aircraft) near village Budjanovci, about 45 km from Belgrade. It was also used to shoot down a NATO F-16 fighter on May 2 (its pilot; Lt. Col David Goldfein, the commander of 555th Fighter Squadron, managed to eject and was later rescued by a combat search-and-rescue (CSAR) mission).[9][10]

      During the war, different Yugoslav SAM sites and possibly the SA-3 also shot down some NATO UAVs.

      "The war (in Kosovo) proved that a competent opponent can improvise ways to overcome superior weaponry because every technology has weaknesses that can be identified and exploited," the jury is still out even on real damage to Serbian military infrastructure, the fact remains that SAM sites forced NATO planes to fly higher and be less effective than they would have been without these defences."

      This does not fit within your arrogant "luck" bullshit.
      These "invisible" planes have been downed by real professionals & as the Serbs say "we didn't see it was invisible".

      baron_rouge, read and understand my comment better especially if the English language is your second language. Thanks.

      This is funny! A Russian is saying it was Chinese, and then we have two Serbs commenting; one confirming what I've said, and the second one is accusing me of being arrogant and talking crap :) I love these Slavs :) Just do not like those who use the Jewish sources :)

      Dear All !!
      Bottom-line, one month later US "mistakenly" missiled Chinese Embassy out of the whole of Belgrade. The rest as they say is all yiddish !

      baron_rouge, my feelings and emotions are cut now :) At least I do not use the Jewish sources like those hoping for WWIII. And Mr Croissant - read it again.

      baron_rouge, "nah mate" its a trained devil assigned to this blog ! They all sit in an open plan office, each has a couple of blogs to disinform?!

      Well... so much money for something what can't work : during the time needed to make the stealth fly, the detection technology has been upgraded and can see it... Quite funny. Now comes the Golden Turkey F-35... well... comes ?

      vendor, In Iraq, old French infantery radars, if somewhat tuned, could see very well the "stealths"... Was quite funny...

      FR : Hey, we see a lot of planes, there !
      US : No... There's nothing at all...
      FR : Then, we engage !
      US : Errrrr... no ! no ! (blush).

      US still hasn't seen a PAK 50 ..

      Yes, it's a bird on their radar

      This has to be one of the silliest articles I've read in a while. China detected some jets flying over the South China Sea. They have no idea what kind of jets they were. Thus the author says that if the jets just happen to have been F-22s, then that means China can detect the F-22. What a way to invent propaganda out of absolute non-information.

      Stealth aircraft aren't invisible. They simply have lower detection signatures making them harder to detect at long distances. Long-waive radar can detect them. But long-waive radar is extremely easy to jam, and is useless for targeting data. All radar homing missiles are dependent on X-band radar. The F-22s X-band radar signature is about the size of a marble. In order to get a missile lock on an F-22 with a radar guided missile, you have to get within a few kilometers. Good luck with that.

      The US military is just getting whomped lately - and the hits just keep on coming.

      vendor, Old radar defeats new tech - that's funny.

      There's probably a lot of things China can do that most people aren't aware of...Russia too.

      Russian mathematician Petr Ufimtsev actually created the concept of stealth in the 1960s. The Soviet leadership didn't want to develop it so he took it to the US. After they developed it, he then came up with a radar system that could detect stealth aircraft. Watch this www.youtube.com/watch?v=lq-xlLcL_1k

      elemental resonance is the particular atomic frequencies of *elements*.

      Thus by understanding the composition(elements & atomic structures)

      Than fine tuneing a *reciever* that picks up on those *tuned* resonances frequencies = detection anywhere. Above land and well below in the deepest oceans.

      Of course in all the atmospheres and beyond.

      Jet fuel can't melt steel beams,

      The best way of course to track the rather expensive US stealth aircraft is to follow the 'trail of bullshit' behind them and then look to the front of the US planes to see where the nearest hospital, water treatment plant or electrical power station is.

      Old fashion WW2 long wave radar has no problem doing it. Russia is building VHF and UHF transmitter/receiver element in the leading edges of the new fighters. Latest software in UHF/VHF signal processing improves the radar information (accuracy) So much for the fabled invisible F-22 and forget that fat flying porker the F-35 that ought to put out of its misery right now.
